Looking back at what I recorded for a jazz-blues playalong thread, I was making up a melody in real time. This is made possible by working on intervals like minor 3rds, perfect 4ths, and so on - knowing how they sound, as well as what they look like on the fretboard. I really had to make up a melody because the backing track was for a generic chord progression, not a real tune or anything. When I slipped in some nonsense scalar run I guess I was just trying to change it up a bit. I find scalar runs to be quite boring and have been working at getting rid of that habit. This tune is was a well known pop hit in the 70s and is still covered quite a bit. Here the first thought was to use the melody as a jumping off point. Here I also worked with intervals as much as I could but it fell apart into a mess at some point.
